[1] Prior service costs are amortized on a straight-line basis over the average remaining service period of employees expected to receive benefits.

[2] The funded status reflected above includes the liabilities attributable to all of the Pension Plans but only the assets of the Retirement Plan as the other plans are not considered funded for ERISA purposes. To provide a source for the payment of benefits under the Executive Supplemental Pension Plan and the Management Retirement Plan, we own whole-life insurance contracts on some of the participants. The cash value of these policies was $29.2 million and $27.3 million at June 4, 2013 and June 5, 2012, respectively. In addition, we held in trust $0.4 million and $0.5 million of cash and cash equivalents as of June 4, 2013 and June 5, 2012, respectively, relating to these policies. We maintain a rabbi trust to hold the policies and death benefits as they are received.
